In the practical embodiment'of my invention, I provide a suitable supporting framework l shown, in the present instance, as

consisting of a pair of side supporting standards 2 connected adjacent to their upper ends by cross pieces 3 and at their upper ends by a head piece 4, but it is to be understood that any suitable type of frame structure may be employed.

Disposed between the uprights 2 of the frame structure is a tilting or oscillating measuring vessel-or receptacle 5, which, as herein disclosed, is of oblong rectangular form, and composed of bottom, side and end walls, the top of said vessel being closed on opposite sides of its transverse center by short walls 6, spaced to provide an'intervening central filling opening or inlet 7. Tie measuring vessel is provided with a central vert-ical partition 8 dividing it into similar measuring compartments or cham'- bers 9 andl 10, oflike capacity, said partitionS extending upwardly from the bottom wall of the vessel and terminating at a suitable distance below the top thereof to leave a space or passage 11 for the flow of the liquid from one compartment or chamber to the other, as hereinafter described. An inverted ll-shaped guide or deflector l2 is disposed within the filling space or inlet 7 and extends transversely across the space 11 at a point above the upper edge of the partition S, the sides of said deflector extending at an outward and downward angle in opposite directions, to respectively guide or deflect the entering liquid into one or the other of the compartments of the vessel.

rlfhe vessel 5 is provided with trunnions 13 arranged in the plane of its transverse axis to engage open bearing recesses in the inneror short arms 14 of a substantially U- shaped balancing or weight beam 15, the long arms 16 of which extend outwardly beyond one end of the frame and receptacle and are connected for movement in unison by a cross bar 17. At the points of junc- Y tion between their longand short arms, the

side bars of the lever, which extend on opposite sides of the receptacle 5, are provided with trunnions 18 mounted to tilt in bearings 19 upon the frame, and at its outer end the lever has suspended therefrom one or moire weights 20, which normally balancethe weightof the receptacle. It will be understood that by this construction and mode of mounting the receptacle, the said receptacle is adapted to tilt in one direction or t-he other froma poised condition on the trunnions 13, when the lever is overbalanced by 'the weight of the liquid in either compartment, plus the added weight of a priming quantity of liquid in the other compartment, as hereinafter described, and that the receptacle is also adapted tovmove vertically with the lever in the swinging movements of the latter. f 4 V y r The respective compartments 9 and 10 of the vessel 1 are each'provided at its outer end with a depressed discharge pit, well or chamber 21, which is preferably of triangular form, its bottom wall sloping outwardly and downwardy, and said well being provided at the point of juncture of its bottom wall and the outer end wall of the compartment with a discharge outlet 22 for the discharge of the measured quantity ofliquid issuing therefrom into a receiving pan or vessel 23, which pan or vessel 23 is supported by the frame-work below the tilting vessel and is provided with a final discharge outlet 24. The discharge of the liquid from each compartment is controlled by a siphon discharge device, generally indicated at 25, and lwhich comprises a central wall or plate 26 and inner and outer walls or pla-tes 27 and 28, extending from side to side of the tilting vessel. The central plate 26 extendsY upwardly from the sloping bottom wall of the well 21 to a point slightly below the level of theV upper edge of the partition 8, and the walls 27 and 28 areV disposed in parallel and spaced relation thereto to provide inner and outer short and long siphon legs or passages 29 and 30, the intake legV 29 of the Siphon being in communication at its lower end with the well 21, while the discharge leg 25 of the siphon communicates at its lower end with the outlet passage 22. The walls or plates 27' and 2S are connected at their upper ends by a top wall or return portion 31, which is spaced from theupper edO'e of the plate 26 to form a connecting passage between the upper ends of said legs, the said wall 31 being arranged slightly above the level of the partition 8. The Vwall 2S is disposed in spaced relation tothe adjacent end wall of the compartment to provide a passage 32 which is in communication at its upper end with the top of the compartment 9 or 10 and at its lower end with the discharge passage 22, the said passage 32 serving as a sealing, priming and liquid-retarding passage, as hereinafter fully described. The upper edges of the partition 8 and partition plate 26 of each siphon are arranged at alevel which coincides with the liquid level of the predetermined 'amount Y lowered and correspondingly raised at the Y outer` end of such compartment, whereby a portion of the liquid will be caused to flow downward and discharge through the paslsage 32 whereby such passage `will be kept constantly primed with liquid, as hereinafter lfully described. When sthe'liquid 1n theffilled compartment reaches the-discharge :level as described, .and the v:weight of .such v liquid .effects a tilting lof the vessel tfor a discharge action, the 'liquid .which V'has reached theilevelofithe top.` ofthesiphon intake leg 29 overflows throughthe top 'con- :necting 4passage 31 into the Siphon discharge leg I30, whereby a siphonicaction is established for the discharge of fthe `Iliquid 'from the compartment, `as will `be readily understood. Normally: each Vcompartment is always'filled withlliquid to a comparatively low orpriminglevel, as showmbyfthe'liquid level gline in fthe .compartment .9 in Figs. "3 and 4, whereby a suflic'ientsupplyfof liquid is maintained vin l each 5 compartment lto fcon- `stantly .keep the fsiphon and passage '32 lprimed ifor action.

rThe discharge ofvthe liquid fromfa `filled compartment .iseffected 'i by :the overflow of the liquid from. such :compartment Athrough the passage -11 ycverthe upper 'edge ofthe .partition 3 into 'the 'opposite-fcompartmenn .the weight ofthe liquid in the lledcompartment, vplus Ythe weight jof the `added liquid flowin into the empty compartment, cau-sing the lled end 'of thetilting vessel to lose its lpoise and overcome fthe resistance of fthe balancing beam Iand weight, whereupon the 'weighted end vof ythe lever will be elevated andthe vessel-willtilt upon vits pivotalconnection so as to lower the trated, `for example, in Figafshowing the vessel 5 tilted in onefdirection for the discharge of the liquid 'fromthe compartment 10. As soon as a certainproportion of the liquid discharges from a filled compartment, however, the vessel til-ts back tothe normal position shown in Fig. l and Fig. 3, in which the balancingfbeam returns toa horizonta position, butthe vesselassumes a position slightly tilted or tinclined to the horizontal .toproperlydispose one or the other of the compartments for cooperation .with a.. feed nozzle vfor the filling ofsuch l,compartment with liquid. The tilting motion ofthe vessel back Ytognormal position from a dischargingV positionis controlled by a pair of fixed stop rlugsorldevicesx33 arranged centrally upon the upper edges of the side walls of the vessel .in line with each other and with the-vertex of the'deflector 12, said :stops33 being fixed and disposed for vcoperation lwith.contactrollcrs 34 carried-by adjustable stop ymembers 35:1nounted upon the head piecea above the side walls o f the vessel. Each lofthese adjustable stop :pieces isA inthe form of a bracket held in position by retaining screws 36 entering threaded open- V:ings Atherein and passing through slots 3T zin the head pieces 4, theopposite ends of each stop bracket being engaged by adjusting screws 38 mounted in lugs 39 `depending fromithehead piece 4. lWhen the vessel is in position for filling the compartment 10,

vthe fixed stops .-33 "engage" the relatively rear faces fof ithe'rrollers 3,4, `so as to .dispose the side of .the deflector overhangmg ysaid compartment 10 `;in position below the liquid lowing vthe Vstops 33 to :pass beneath the rollers 34 tothe opposite sidefthereof, whereupon'the vesselfis .free-to tilt tothe position vsho-w11 in Fig. '4 for the discharge of the liquid V:from the compartment 10. lVhen lthe Vessel tilts back againto normal .posi- `tion, it will be evident that the central portion of the vessel will be raised-by the upward :movement of the short arms of the .mann-whereby the stops 33 will be brought.

into position toen-gage thesides of the rollkers 3a opposite those with which the fixed stops a-rein contact. in Fig. 3, by which the vessel will be held in the reverse normalljv inclined position to that shown in Fig. 3,

thus'lbringing the side of the deflector l2 overhang'ing the compartment 9 into position below the nozzle 4:0 for'the discharge ofthe liquid therefrom into said compartment 9,'theaction of the stop mechanism thus being to govern the tilting motions of the vessel :so as to alternately dispose the same in reverse slightly inclined or tilted filling positionsfor coperation with the nozzle 440 tto alternately fill the compartments in the measuring operation of the device. By the adjustment of the adjustable stops 35 in one direction or the other, the tilting motions of the vessel may be controlled to secure a'poise in the event that there should be anyslight vdiscrepancy in weight between the respective'ends of the vessel. VWhen the vessel is ineither of its normaltilted filling; positions,one or the other-of the walls 6 will engage and coperate with the adjacent cross piece 3, at the time the stops 33 are .ini engagement `with the surfaces of the rollers 34 to :stably maintain the receptacle in iilling position during the filling of a compartlment with liquid up to the discharge eve ivi

It will thus be understood that the degree of inclination of the vessel, when the stops 34 are in engagement with the stops 33, during the time that the liquid overflows over the wall 8, affects the volume of contents in the filled compartment in proportion; and that by varying this inclination through the adjustment ofthe stop member 35 the measuring capacity of the compartments can be accurately standardized without having to resort to displacement bobs even in the Y event of a variation in the sizeof the respectiveV compartments.

The feed nozzle 40 is tapered from a cylindrical form at its upper end to a flattened forni at its 'lower end, which provides an elongated and constricted discharge passage of a length slightly less than the width of the receptacle 5. This constricted outlet provides for the flow of a liquid at a given pressure. In general, where the liquid to be measured has a nearly constant pressure, the

V:flow to the apparatus can be'regulated by the size of the discharge outlet of the feed nozzle and a controlling valve placed in the fluid supply pipe 41 leading from the source of fluid supply to the apparatus. However, where there is a great variation in the pressure of the liquid, provision must be made for regulating and controlling the same in order to prevent the compartments from being flooded by the delivery of too great a quantity of liquid. I, therefore, provide a pressure controlling device, generally indicated at 42, whichV is interposed between the supply pipe 41 and the feed nozzle. This device consists of an upright cylindrical casing 43 having at its upper end an air vent aperture 44, the wall of which is tapered to form a seat 45, and having its lower end internally Vtapered for engagement with a union or coupling member 46 connecting said casing with the feed nozzle. The casing is provided at a suitable elevation with an annular enlargement 47 forming a liquid inlet chamber and which is provided with a lateral inlet 48 for connection with the supply pipe41. This receiving chamber is'normally in communication with ports 49 in a pressure controlling valve 50 mounted for movement within the casing. The pressure controlling valve comprises a tube or cylinder closed at its upper end and open at its lower end, the upper portion of said tubeV being separated from the lower portion thereof by a partition or diaphragm 51. The' lower portion ofthe tube thus separated from the upper portion, and which is provided with the ports 49, forms a conductor for the flow of the fluid from the chamber 47 to the feed nozzle. A projection 52 is provided upon the upper closed end of the vvalve tube to engage the seat 45 and close the vent 44 when the valve tube reaches the limit of its upward movement, said tube being limited in its downward movement by the union or coupling 46. y

In the operation of the pressure controlling valve, liquid under a determined pressure is admitted thereto from the chamber 47 through the ports 4.9 for supply to the feed nozzle. As long as this pressure of the liquid remains below that required for the proper volume to be discharged by the constricted nozzle, the flow valve remains undisturbed in the normal position shown in Fig. 8, but the instant the flow into the valve increases, due to a rise of pressure, the liquid rising in the valve against the partition 51 will force the valve to rise Yand inV so doing will close the ports 49 to a proportionate degrec, and thus regulate and govern the liow of liquid to the nozzle.

In the operation of the device, the vent 44 provides for the admission and escape of air and any liquid which may flow upwardly between the valve and casingin the Vup and down movement of the valve, but if desired a by-pass tube or pipe 53 may be provided for the return of the liquid to the inlet 48.

An important feature of this measuring apparatus resides in the fact that the measuring action is by volume and not by weight, the central partition 8, whose height controls the volume contents of both compartments, causing the production of a most accurate measuring device for the Yreason that when the liquidin one compartment reaches the level of the top of the partition it begins to overflow into the neXt compart- 100 ment, and as the vessel cannot discharge the contents or any part thereof without overbalancing the set weight 20, which is fixed to balance a weight equal to the vessel plus the weight of the volume ofthe liquid of a 105 filled compartment, and plus an approximate predetermined quantity of overflow, it is evident that the volume of the filled compartment thus obtained at each discharge will'be the same. In this apparatus the par- 1 10 tition 8 operates in conjunction with the oscillating action of the vessel to automatically perform what is possible with an ordinary gallon or other measure by hand, z'. e., the pouring of the liquid until it reaches and 115 runs over the edge of the measure, thus obtaining an equal volume of liquid at each operation, or, in other words,.an exact quantity. Y Y Y An important advantage incidentrto the 120 use of Siphon discharge devices of the character described is that long and narrow Siphon legs, extending the full width of the measuring vessel, are provided so as to secure a siphon of large capacity, requiring 125 only a minimum of head of liquid to submerge it completely, and whose legs offer a very large frictional surface to a narrow column of liquid, which prevents the falling through or breaking up of the liquid in its 130 drical; Siphon: of the same area. Also bythe..

use of a iattened siphon the degree of2 tilt.

- ofthe vessel'requinedito=floodthesiphon for a discharge action` iszreduced to. a; material extent in, comparison with cylindrical siphons, whereby a.mone.1r eliahle, efficient andy sensitive action. of; the. measuring` vessel is obtainedi l Another impnrtant featurev of. my.y invent tion resides ini thevl provisom of: thesealingn primingandf liquid`l netarding passage ,32 in connection. with; eaclnsiphomthe use and: ad;-

As a. result of. this action the flow; of," the liquid through/the down leg ofV thesiphon will be retarded by the. iQW off the liquid through the outer; leg orV passage 32, thus assuring ample timey fOl the. dOWIl. 19g; t0

This eiiiciency of action of the measuring vessel is increased byl the'use of perforated baiiie plates 54 within the .compartments 9 and l0.V 'These bailie platesare spaced from the top and bottom walls of the-compartments, and extend from side to side` thereof, and are perforate thnougliout andriseto a level above the level of; the partition. 8. The baffle plates are intendedfor use-where the liquid to be measuredfv has a; tendency to foam, and their purposeistokeep thegreater part of the foam formedf while'the liquid is falling-into the receptacle away fromthe siphons and forcingfthe sameto overflow` from the compartment which is being: filledi into the other compartmentthus:allowing the foam which accumulates within the inactive compartmenty to settle'beforesuch compartment is lled andready to discharge. The perforatio-nsin thepantitions permit the clear liquid toifiow; freely,l so that the discharge action isnot-inberferedewith, while the choking of the. siphonsfwith. foam will be eifectually prev,en-ted:v

In connectionv with the apparatus, I'provde anindicatingmeans, for indicating the number of times: the vessel isztilted, and consequentlgyfthe number of volumes offliquid, and total amount of the liquid, which is VmeasuredanddispensechA I; alsoprovide for operation in conjunction with this indicating; device a, stopmechanism which may be setgto; permit thevessel to. tiltV a predetermined number' of timesandto then lock ity against further movement, while simultaneouslycutt-ing off` thesupply of liquid. The

indicating andi stop mechanism disclosed for.

thiszpunpose comprises alever55 fixed at one-y end.l to the shaft; 56 of an indicator 57, containing indicating mechanism of any desined character, and; provided at its opposite or ende with a, dog onpawl 58to engage the teetlifl 59' of a ratchet; wheel 60. The ratchet wheel GGisiiXed upon a shaft 6l on which isloosely mounted a. circular disk 62" and backward feed and,y return action to the.

pawl.A By this means the ratchet wheel and stopdisk will: be turnedy a distance of a ratjx'zhet toothv on each tilting movement of the vessel, and simultaneously the indicator willi beoperated. The locking arm 65 pro- Lio Vjects from a locking lever 66 provided at The disk 62 may be set so that its notch 63V coincides with any of the ratchet teeth, for a stopping motion after a predetermined number of tilting movements of the vessel, and as the'arm 65 s set to support the lever 66 from the'disk V62 `and rides upon the periphery of said disk,it will be evident that the ratchet wheel will be free-to turn until the notch 63 Acomes into engagement with the arm65,rwl1ereupon said arm will drop down into said notch, thus allowing the lever 66 todrop and close the valve to cut ott the lowof liquid. The machine may therefore be setto dispense any desired amount of liquid and its operation will be automatically arrested whensuch amount of liquid is measured and dispensed by the stop mecha# nism in an obvious manner. It will, of course, beV understood that any suitable 'means may be employed to x the notched' disk'in position upon its shaft after having A been set or adjusted.
